一类图的孤立控制集的个数

On the number of isolate dominating sets of certain graphs

Nima Ghanbari, Saeid Alikhani

摘要:

设$G=(V,E)$是一个单图. $G$的支配集是子集$S\subseteq V$,使得不在$S$中的每个顶点与$S$中的至少一个顶点相邻。$G$的最小控制集的基数,记为$γ(G)$,是$G$的控制数。如果诱导子图$G[S]$至少有一个孤立点,则称$S$是$G$的孤立控制集.孤立控制数$γ_0(G)$是$G$的孤立控制集的最小基数。本文对几类特殊图的孤立控制集的个数进行了统计。

英文摘要:

Let $G=(V,E)$ be a simple graph. A dominating set of $G$ is a subset $S\subseteq V$ such that every vertex not in $S$ is adjacent to at least one vertex in $S$. The cardinality of a smallest dominating set of $G$, denoted by $γ(G)$, is the domination number of $G$. A dominating set $S$ is an isolate dominating set of $G$, if the induced subgraph $G[S]$ has at least one isolated vertex. The isolate domination number, $γ_0(G)$, is the minimum cardinality of an isolate dominating set of $G$. In this paper, we count the number of isolate dominating sets of some specific graphs.
